Abstract: PURPOSE: A method for detecting a cut-off call in a switching system is provided to offer an exact performance of a switching system by exactly detecting a cut-off call. CONSTITUTION: If a switch is connected, an upper call control processor informs a lower call control processor that the switch has been connected(200). The lower call control processor monitors the operations of the switch every 5 seconds and checks whether a cut-off call is generated. If a cut-off call is generated, the lower call control processor notifies the upper call control processor that the cut-off call has been generated(202). The upper call control processor increases a count value for the cut-off call by '1'. Then the lower call control processor checks a connection state of the switch at the next period. In case that the generated cut-off call is released, the lower call control processor sends a cut-off invalid signal to the upper call control processor(204). The lower call control processor initializes the increased count value according to the cut-off invalid signal. Continuously the lower call control processor checks whether a cut-off call is generated. If a cut-off call is generated, the lower call control processor notifies the upper call control processor of the generation of the cut-off call(206). The upper call control processor increases a count value for the cut-off call by '1'. Then the lower call control processor checks whether a cut-off call is generated at the next period. If a cut-off call is generated, the lower call control processor reports it to the upper call control processor(208). Accordingly the upper call control processor increases a count value for the cut-off call by '1'. At this moment the upper call control processor checks whether the increased count value is a preset value. In case that the increased count value is a preset value, the upper call control processor informs a status management processor that the cut-off call has been generated(210).
